In some examples, a system to produce refined location information for multiple vehicles may aggregate GPS coordinates collected from each of multiple devices over a period of time, estimate a location for each of the multiple devices at intervals during the period of time, track the locations for each of the multiple devices over the period of time, and determine a current location, on a road, of the vehicle corresponding to each of the devices based on a detected trend of the tracked locations for each of the multiple devices over the period of time.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of location refinement, the method comprising: aggregating global positioning system (GPS) data, received from each of multiple devices that are proximately located relative to at least one other of the multiple devices, over a period of time; estimating a location for each of the multiple devices at intervals during the period of time based on, at least, the aggregated GPS data; determining a current location for each of the multiple devices based on a trend of the estimated locations for a respective device, for each of the multiple devices over the period of time; refining the determined current location of a vehicle that corresponds to a particular one of the multiple devices, relative to a road, by comparing the determined current location for each of the multiple devices.
2. The method of claim 1 , wherein the method is executed by a server.
3. The method of claim 1 , wherein each of the multiple devices is located within a predetermined distance of the at least one other of the multiple devices.
4. The method of claim 1 , wherein each of the multiple devices is disposed in a corresponding vehicle on the road.
5. The method of claim 1 , wherein the refined location of the vehicle includes an indication on which lane of the road, the vehicle is currently located.
6. The method of claim 5 , further comprising: informing the particular one of the multiple devices of the refined location of the vehicle.
7. The method of claim 5 , further comprising: mapping relative refined locations of multiple vehicles that respectively correspond to one or more of the multiple devices.
8. A system to produce refined location information for multiple vehicles, the system comprising: multiple devices, disposed with respectively corresponding vehicles, each configured to record GPS coordinates at multiple intervals over a period of time; and a server configured to: aggregate GPS coordinates collected from each of the multiple devices over the period of time, estimate a location for each of the multiple devices at the multiple intervals during the period of time, track locations for each of the multiple devices over the period of time, determine a current location, on a road, of a vehicle corresponding to each of the multiple devices based on a detected trend of the tracked locations for a respective device, for each of the multiple devices over the period of time, wherein the determined current location includes an indication on which lane on the road, the vehicle, that corresponds to each of the multiple devices, is currently located and transmit the current location, at least relative to the road, to at least one of the multiple devices that corresponds to one of the multiple vehicles.
9. The system of claim 8 , wherein the server is further configured to collect the GPS coordinates that are transmitted from each of the multiple devices to the server.
10. The system of claim 8 , wherein the server is further configured to collect the GPS coordinates that are stored on each of the multiple devices.
11. The system of claim 8 , wherein the server is further configured to generate a map that includes the determined current location of each of the multiple vehicles that corresponds to each of the multiple devices, relative to each other.
12. The system of claim 8 , wherein the server is further configured to: refine the determined current location of the vehicle that corresponds to each of the multiple devices, relative to the road, by comparing the determined current location for each of the multiple devices.
13. The system of claim 12 , wherein the refined current location of the vehicle that corresponds to each of the multiple devices includes an indication on which lane of the road, the vehicle is currently located.
14. A method of location refinement, the method comprising: aggregating data pertaining to each of multiple devices that are proximately located relative to each other, over a period of time; estimating a location for each of the multiple devices at intervals during the period of time; determining a current location for each of the multiple devices based on a trend of estimated locations for the respective devices, for each of the multiple devices over the period of time; and refining the determined current location of each of the multiple devices, relative to each other, by comparing the determined current location for each of the multiple devices.
15. The method of claim 14 , wherein the data pertaining to each of the multiple devices includes an IP address.
